@Alexis
I suspect you would like the performance of the Apollo better because it is noted to be slower by a few seconds. There are also 2S battery version portables that will be a lot tamer than the JarHead. Although I must say, if you put a JarHead up for sale, I don't know how it would last long.
I use to 'stir' mid-bowl. I haven't had to do that lately. I also haven't had combustion events. I attribute this to tuning the IH. When it clicks it is perfect, in other words. I use a 7-8 second heat-up cycle and it is very well done. And I immediately go for a 3-count dip at least twice... all for the same draw. At the end I assess by removing the cap and inspecting the bake. On de-bowling, there is some difference but not enough to fret over. It'll spice up the ABV. I do this with a '18 tip and cap, by far the hottest coupling option. I warn about the '20 VC and IH only to say check with others.
I tune the IH 2 ways - 1, time to proper temp [not just a click] is voltage and coil related. Apollo should slow the bake for you. The coil position is 2. Not easily adjustable but this is how to time the clicker with the right bake. Fluxer has this figured out so the user can adjust. You can adjust the Caldron and the PSM. The MagHeater has an adjustment lever built in. Apollo hasn't weighed in on this option as yet.
And stay tuned. Within a month Dynatec is announcing 2 new models. This is getting exciting because Fluxer to is talking a new release.
Hey thanks very much for your reply and detailed insight. Much apppreciated. The basic flaw with the Jarhead in particular, and maybe other models I wouldn't know- it heats the tip of the cap only, or at least primarily.
Which means that whenever I was using the Jarhead, it was essential to always go past the click. I hate getting almost invisible hits after a click.
With my torches, preferring single flame lately, I can pretty much guarantee every hit is more or less equal, and just right in terms of size, density without being too harsh or hot for my sensitive allergy prone lungs.
I NEVER combust with a torch. Not for a couple years now, except maybe one event when music was loud, doh!
.
But with the IH, stopping at or just shortly after the click, never gave me a satisfying, and always very unpredictable hit.
2.5 seconds past click would be almost right, but a fraction over led to frequent combustion. Or underwhelming, wispy vapor.
I could never consitently draw that line right. I had to really concentrate, with anxiety about the timing.
My judgement would decline as effects increased, hence more combustion, which often was the result of overcompensatiing after one or two unsatisfactory hits.
I always found my top charred, and green nearer the bottom.
Pipes told me to adjust the depth of the coil in the glass. Indeed, lower down takes longer to click, and supposedly heats further down the cap, less focussed on the tip.
Howevere I still never got it right. I felt I was missing out on what the vapcap gives me. And the taste was less pleasant.
And yes sure, I have no doubt many people would snap my hand off for it. I barely used it, stored clean since 2016, I only plan to sell it but have been so unwell for recent years only daily essentials have been on the cards.
I would only want about £50 plus shipping for the unit, much cheaper than the current, newer high tech alternatives. I do hope to find an appreciative new onwer for it sooner or later.
In the meantime, one day at a time, simple survival is the name of the game.
@TommyDee thanks again mate for your thorough reply, hioe you are well.
